Good bye to the class

 I have studied English in the English 3A class since October in 2014. In the class, I have studied many things.
 For example, I studied "MARGINS". MARGINS is the blanks on the both ends of the document. For the first time, I could not obey the law of the MARGINS. But I can do that now.
 Secondly, I studied topic sentence. Topic sentence means the sentence which describe the topic of the paragraph.
I have studied a lot of things in the class, so I am going to study English more hard using the knowledge I have studied in this class.
